Greater Western Sydney recruiting assistant Paul Brodie has resigned after being caught betting on AFL matches, including one involving the Giants.

Brodie has been banned for 13 months after it was revealed by the AFL he took out a $100 multi-bet on five matches during round 19, 2015.

One of those legs included a GWS game.

• Hawks, Tigers win in dual-bye 2016 AFL fixture
• AFL players have the right to choose their employer
• Why Harley Bennell is boom or bust for Freo

In a statement, Mr Brodie said he regretted the decision he made.

“I have made a mistake which has let the club down, let down my family and friends, and let myself down, ” Mr Brodie said.

“I am very sorry for the lack of respect I have shown for the rules and principles that maintain the integrity of our game.

“I will accept whatever sanction is imposed on me as an appropriate penalty. I have learned a serious lesson and hope others can also learn from my mistake.”

GWS CEO David Matthews said the situation was a “poor error of judgment”.

“The rules relating to betting are clear within the AFL competition,” Mr Matthews said.

“Paul knows he made a very poor error of judgement and as such we have accepted his resignation. Any action that has the potential to undermine the game’s integrity is clearly unacceptable and the consequences are rightly severe.”

Brodie’s ban from participating in football expires on December 1, 2016.
